Question

运行retrofit 2.3的我的Android应用程序，当我给它一个带有服务器IP地址的URL时，我不会将我的GET请求发送到我的HTTP服务器。

当我在笔记本电脑，手机或Android工作室模拟器上的浏览器中尝试使用URL时，我的服务器得到了正确的响应。

所以我添加了一个okHttp拦截器记录器，所以我知道网络上发生了什么。它会在日志中打印出来：

okHttp log
D/OkHttp: --> GET https://IP/stuffworks?a=7u http/1.1
D/OkHttp: --> END GET
D/OkHttp: <-- HTTP FAILED: java.net.SocketTimeoutException: connect timed out

这是我在Android应用程序中的实现（当测试call.enqueue总是转到onFailure和Toasts＆＃34;错误：（＆＃34;

//Retrofit network method
private void beemMeUp(String ipAdress, String attributes)
    {
        HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
        // set your desired log level
        logging.setLevel(HttpLoggingInterceptor.Level.BODY);

        OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
        httpClient.addInterceptor(logging);

        Retrofit.Builder builder = new Retrofit.Builder()
                .baseUrl("https://" + ipAdress + "/")
                .client(httpClient.build())
                .addConverterFactory(GsonConverterFactory.create());

        Retrofit retrofit = builder.build();

        SiloClient client = retrofit.create(SiloClient.class);
        Call<SiloSensorReport> call = client.report(attributes);
        Toast.makeText(this, "https://" + ipAdress + "/" + attributes,                      
        Toast.LENGTH_SHORT).show();

        call.enqueue(new Callback<SiloSensorReport>() {
            @Override
            public void onResponse(Call<SiloSensorReport> call, 
        Response<SiloSensorReport> response)
            {
                SiloSensorReport repos = response.body();

                textView.append(repos.toString());
                Toast.makeText(MainActivity.this, "success :)", 
                Toast.LENGTH_SHORT).show();


            }

            @Override
            public void onFailure(Call<SiloSensorReport> call, Throwable t)
            {
                Toast.makeText(MainActivity.this, "error :(", 
                Toast.LENGTH_SHORT).show();

            }
            });
        }

    }

地址应该是：

http://IPaddress/attribute

例如：

http://123.45.67.12/stuffworks?works=true&value=87

我的服务器代码

server.on("/stuffworks", stuffHandler);


void stuffHandler()
{
  Serial.println("User requesting stuffworks page!");

String message = "";
  for (int i = 0; i < server.args(); i++)
  {
    Serial.print(server.argName(i));
    Serial.print(": ");
    Serial.println(server.arg(i));
    message += server.argName(i) + ": " + server.arg(i);
    message += "<br>";
  }

  server.send(200, "text/plain", "it works<br>" + message);
}

P.S。更改URL以使用http：//而不是https：//我看到我的服务器打印它得到了一个GET请求，并在使用okHttp记录器捕获的客户端上得到了回复。

D/OkHttp: --> GET http://192.168.43.223/stuffworks?a=val http/1.1
D/OkHttp: --> END GET
D/OkHttp: <-- 200 OK http://192.168.43.223/stuffworks?a=val (50ms)
D/OkHttp: Content-Type: text/plain
D/OkHttp: Content-Length: 22
D/OkHttp: Connection: close
D/OkHttp: it works, a: val
D/OkHttp: <-- END HTTP (22-byte body)`

但是我仍然有一个问题，call.enqueue总是转到onFailure并打印错误:(即使我得到了服务器响应

Retrofit 2连接到本地服务器，响应失败，连接超时
